Trouble with new Meyer 6M New York mouthpiece

Hi everyone, I’m an alto sax student (1 year playing) and just bought a Meyer 6M New York on my teacher’s recommendation. I’ve been having nothing but squeaks and can’t get a stable tone. I’m still within the return window, so I’m wondering if I should send it back and try something else :/

I’ve made three quick recordings of the same tune with different setups to compare (all on my Buffet alto):

1. Meyer 6M New York + D’Addario Royal 2.5 (lightest reed I can handle)

2. Yamaha 5C + D’Addario Royal 2.5 (same reed as before)

3. Yamaha 5C + D’Addario Organic Unfiled 3S (my default configuration)

Questions:

• Is the Meyer 6M too “big” for a beginner?
• Should I return it and try a different jazz piece, or stick with my Yamaha 5C for now?
• Any mouthpiece/reed combos you’d recommend for early-intermediate jazz on alto?

Thanks in advance for your insights!
